Title: Manufacturing device for hydrodynamic grooved bearing
Inventor: HONDA HIROHIKO
IPC: F16C33/00
Filed: 1987-03-13
Abstract: PURPOSE:To change the depth of a groove formed on a bearing bush by providing semicircular axial grooves gradually changing in the groove depth in the longitudinal direction of the center line on the outer peripheral surface of a guide pin, thereby changing the axial positions of the guide pin and a cage. CONSTITUTION:Semicircular axial grooves 3A, 3B disposed on the outer peripheral surface of a guide pin 3 are formed in such a manner as to gradually change in the groove depth in the longitudinal direction of the center line. Balls 4A, 4B put in the respective spaces formed by the grooves 3A, 3B and holes 5A, 5B in such a manner as to freely roll have a diameter larger than the wall thickness of a cage 5 and a radius equal to or a little smaller than the radius of the semicircles of the grooves 3A, 3B. Further the balls 4A, 4B are formed by material harder than that of a bearing bush 2. When the balls 4A, 4B are thus put in the grooves 3A, 3B, the axial positions of the guide pin 3 and the cage 5 are relatively changed to change the depths of the grooves 3A, 3B in which the balls 4A, 4B are caught, so that the depth of a dynamic pressure generating groove 2A formed on the inner peripheral surface of the bearing bush 2 is changed corresponding to the above change of the groove depths.

Title: Resist applying apparatus
Inventor: MIKANOHARA MASAKO
IPC: H01L21/027
Filed: 1985-03-25
Abstract: PURPOSE:To prevent any unrequired resist splittings from being produced after the resist applying process, by providing means for removing the resist adhered on the peripheral face of a plate. CONSTITUTION:The present resist applying apparatus is provided with an arm 7 moving along the peripheral face of a plate 3 and with a wiper 8 fixed at the tip end of the arm. The plate 3 generally has a square shape and the arm 7 is adapted to move along the peripheral face of the square plate 3. This means that the movement of the arm 7 is confined to linear reciprocating movements along a groove 9. Since the groove 9 is provided in parallel with one side of the square plate 3, one advancing movement of the arm 7 removes the resist from one side of the square. When the resist removal from the one side is finished, the square plate 3 is rotated by 90 deg. by means of a rotating device and the arm 7 moves backward. Thus, all the resist on the four sides of the square plate 3 can be completely removed by two reciprocating movements of the arm 7.

Title: Semiconductor laser
Inventor: NIINA TATSUHIKO
IPC: H01S5/223
Filed: 1982-04-09
Abstract: PURPOSE:To obtain a long life semiconductor laser which does not show any thermal deterioration and crystal distortion due to difference of thermal expansion coefficients and also has excellent heat radiating characteristic, by forming a buried layer of cap layer with a Ca-doped ZnSe. CONSTITUTION:A buried layer 7 of a cap layer 6 in a semiconductor laser is composed of a Ca-doped ZnSe and therefore it has a lattice constant and thermal expansion coefficient which are almost equal respectively to that of an oscillating layer 2 consisting of GaAl As system material. Therefore, crystal distortion is not generated in the oscillating layer 2 and thermal deterioration is also not generated in the oscillating layer 2 because ZnSe can be grown even under a temperature as low as 400 deg.C by the molecular beam epitaxial growth method. Moreover, since ZnSe has a very high thermal conductivity, there is no fear of generating breakdown of semiconductor laser due to a heat generated during continuous oscillation. In addition, since a buried layer 7 consisting of ZnSe to which Ga is added is n type, electrode is respectively formed on the surface of cap layer 6 and rear side of substrate 1 and a forward bias is applied across these electrodes. As a resutl, the buried layer 7 substantially has a high resistance value. Therefore, an applied current is squeezed by the buried layer 7 and the main current path is formed just under the cap layer 6.

For example, a chitosan perchlorate is obtained by making an acetate of chitosan, suspending it with conc. acetic acid, adding perchloric acid thereto.  A chitosan oxide compound is prepared by adding an oxidation agent to oxidize the chitosan perchlorate, filtering and separating it, dissolving the solids in an alkali solution, adding methanol thereto, then adding acetic anhydride thereto, acetylating and desalting the resulting product.

Title: Signal procession device

IPC: G06V10/28
Filed: 1980-05-09
Abstract: PURPOSE:To obtain an accurate slice signal, by using a memory device, where the initial value and distortion of an analogue video signal are stored, as the storing and reproducing means. CONSTITUTION:For every analogue video signal AVS coming repeatedly, a clock CLK1 are counted up during the initial period by a reversible counter 71. This counting-up is continued until the initial value becomes equal to the output voltage VDA of a D/A converter 72. The value of the counter 71 at this time is stored in a memory device 74. After that, the voltage VDA is caused to follow the waveform of a signal AVS by comparison between the signal AVS and the voltage VDA. The output signal of a comparator 73 at this time is stored as a distortion value in a device 74. Next, this value is read out to an S/P converter 75. After that, the output of the converter 75 is loaded to the counter 71. Next, the distortion value stored in the device 74 is read out to control up-and-down counting of the counter 71. Consequently, the converter 72 outputs the voltage VDA equal to that at the storage time. This voltage VDA is converted to a slice signal VSS by a voltage divider 77 and is outputted.
